RESLIENT NONINFLATABLE TIRE.

Application ld llctober 29, 1939. Serial No. 334,295.

To all wliom t may concern.' i

Be it known that l, ALBERT L. AUSTIN, a citizen of the- United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Resilient Noninflatable Tires, of which the following is a specification.

My invention relates to improvements in resilient non-inflatable tires, the improved tire embodying improved' transversely inclined web members carried within the tire casingy in lieu otl the ordinary inner tube With its chamber oi' compressed air and being designed to impart the requisite resilency to the tire as a Whole in taking up or absorbing obstructions andv shocks similarl to the ordinary pneumatic tire, but without the attendant liability to` punctures, blo\vouts and the'like.

The primary object of the invention is to provide a generally improved resilient tire of this class which will be exceedingly sin|- ple in construction, cheap of manufacture and eiiieient in use.

A further object of the invention .is the provision 'of anl elastic non-inlatabletire of suitable resilient material, such rubber, or the like, made up of a suitable tire casing and interiorly arranged substantially regularly spaced relatively movable web meinbers connected to the tread heel and side portions of the tire casing.

A still further object is the provision of a generally improved non-inflatable or socalled airless tire through Ithe provision of improved internally arranged cushioning and reinforcingr web members so constrlufted. arranged and disposed relatively to each other and the tire tread and heel portions ot' the tire that the general line or plane ot compression at the tread or contact portion of the ltire with the vsubiacent surface or roadway will be uniformly received ou a plurality of said web members in the form of a general edgervise comprcssion on two or more ofsaid web members att-he same time, the arrangement being such that as the general Center of the plane olf compression isv beneath the center ot one web and moved forwardly by the rotation of the tire and over the remaining or halt portion oi such weh and the terminal portion ot an adjacent web, the plane of compression is also being carried over the .initial portion of the oppo site side or adjacent web so that a uniform resiliency imparted by the tire as a whole. T he above arrangement and connection of the web members also enables the latter to better receive and cushion the circumferential strains and stresses given to the tire during the active traction or braking movements on the traction Wheels, and reduces to a minimum any liability of -the webs to break away from the tire casing, as contradistinguished from a, general tansverse arrangement of the internally arranged rein forcing and cushioning' Webs or elements heretofore attempted `in tire cores or fillers.

With the above mentioned and other ends in view, the invention consists in the novel construction, arrangement and combination ot parts, hereinafter described, illustrated in some of its eu'lbodinients in the aceom-y panying drawings, and particularly pointed out in the appended claims.

Referring to the drawings', forming a part of this speciiication, Figure l, a. perspective view ot Va tire oth the straight sided heel type constructed in accordanoe'with my invention, a portion ol" the casing walls and reinforcing Iand cushioning vveb members being cut away and shown in sectionfor the purpose oi clearer illustration oi the part-S.

Fig. El, a cross sectional view taken on line 3 3 ot Fig. 2.

Fig. 4., a cross sectional vierv of the same, taken on line #.ll otl Fig. L., and showing my invention embodied in a tire ol' the clencher or beaded heel type.

Similar numerals of reference designate like parts throughout all'the ligure-s oil the drawings.

The tire casing or shoe l, may be of any' suitable and convenient form and comprises a tread portion l, with suitable side walls terminating in tire heel members ll. The heel membersv\ll, may be of the straight sided type, as shown in Figs. l to 3, inelusive, ot tln` drawings, or. it desired. may be` of the clench'er or beaded type, as shown in Fig. 4., of the drawings.

As a means oi connecting, reinforcing and cushioning and strengthening the various tire parts, and particularly as a means of preot the saine,

viding for uniform resiliency to the tire body as a whole, the tire casing is provided with a plurality of internally arranged radially/A, extending transversely inclined web members 2. 4

By reason of the transverse inclination of the web members the latter are of elongated disc or curved ellipsoidal shape, as shown most clearly in Fig. L of the draW- ings, the web members being arcuately curved with respect to the wheel or tire center and spaced apart forming intervening air spaces or pockets 2a, said air spaces or pockets 2a, extending vertically from the tread portions of the tire and communicating with the heel portions thereof, shown most clearly in said Fig. 1, of the drawings.

When mounted upon the wheel rim theair spaces 2a, will be closed and sealed, .or substantially so, The web members 2, and air' pockets 2, are adapted to afford the requisite resiliency to the tire as a whole in taking up or absorbing shocks similar to the ordinary pneumatic tire, and the webs 2, are also adapted to receive thel lateral and circumferential strains and stresses on the tire or casing. as well as to provide the requisite resiliency between the various parts in supporting the super-posed load on thc tire.

The transversely inclined supporting and connecting webs 2, are preferably arranged in radially extending planes, shown, so as to directly receive an endwise compression at at the contact portion at the tread of the tire with the subjacent surface or roadway, and

a means of uniformly distributing the resistance and resiliency offered by such spaced web members 2, the latter are preferably elongated in curved or arcuate ellipsoidal form andtransversely inclined so that the transverse central line of compression, as indicated at the line 5%3 of Fig. 2, of the drawings, will always rest upon or include a plurality of the web members 2, and it will be obvious upon reference to said Fig. 2, of the drawings, that as the tires move in the direction. indicated by the arrows, the lineof compression being as indicated at 3 3, or at the center of one of the web members and upon being moved forwardly by the rotation of the/'tire it will be observed that as the line of compression is moved over the last half or portion ofl the central wel member and the remaining portion of an adjacent web member, it is being carried over the initial and first portion of the opposite or adjacent side web'member so that a uniform resiliency is constantly given to the tire as a whole.

It will also be ol'iserved upon reference to Figs. l, 3 and 4, of thtl drawings that the jspaced web members 2, not only extend between the walls of the tire casing, but that the same' are connected to and bridge the space between the heel portions of the tire and extend flush with such heel portions whereby all of the tire parts or walls are resiliently connected and reinforced and the line of tread compression on the tread portion ot' the tire is uniformly received and cushioned edgewise on a plurality of such web members. It will also be observed that the form and relation of the web members to each other and to the adjacent walls of the casing are such as to cause the same to uniformly receive the plane or line of tread compression on a plurality of said webs and to cause the latter to receive and cushion the circumferential strains and stresses given to the Atire as a whole when used on a traction wheel during active tractive movements or during braking movements of such traction wheels.

From the foregoing description, taken in connection with the accompanying drawings, the operation and advantages of my invention will be readily understood.

Having thus describedvsome of the embodiments of myinvention, without having attempted to set forth all the forms in which it may be made, or all the modes of its use, what l claim and desire to secure by Letters Patent, is,-
